Sluggish? It's near instantaneous at everything, except when it's doing network operations. It literally does a keyword stem search on a 4GB mailbox in under a 1/10 of a second. That's the fastest inverted index lookup I've ever seen - all accomplished with just sqlite. I consider it amazing. It makes the old version of Outlook look like a dog. A one legged dog. And the leg is broken. As others have noted, as soon at it has to access the network it slows down. A lot. And it you queue up enough operations, it can get confused - particularly if the network drops out in the middle and it has to re-sync everything. But it is imap, so I forgive it. To get it's native non-networked speed, you do have to ensure every folder is downloaded to local storage. Do that, and it's amazingly quick.
